Description

  The present invention relates to a simple toilet, and more particularly to a simple toilet that is made of cardboard and a plastic bag and is portable and portable.

  2. Description of the Related Art Conventionally, various simple toilets have been provided in which a plastic bag containing a water-absorbing polymer is stored in a box made of cardboard. As a urine storage bag of this kind of simple toilet, the one described in Patent Document 1 is known, which uses a normal plastic bag, and is marketed with a string for binding the opening of the plastic bag. . In addition, a plastic bag in which a string is drawn around the opening in a drawstring manner is also commercially available.

However, conventional simple toilets have poor sealing of the opening of the plastic bag after use, and have a bad odor and leakage of filth. Moreover, as described in Patent Document 1, a plastic bag that is considerably larger than the box is used, which is uneconomical. Furthermore, since the weight of a human body acts at the time of use, the box needs to have sufficient strength. However, this point has not been taken into consideration in the past.
Japanese Utility Model Publication No. 56-97094

  Therefore, an object of the present invention is to provide a simple toilet which has a reliable and hygienic seal after use, does not use an unnecessarily large urine storage bag, and has a sufficient box strength. is there.

In order to achieve the above object, a simple toilet according to the present invention is:
An outer box surrounded by a plurality of vertical surface portions made of corrugated cardboard, a bottom surface portion and a toilet seat portion foldably provided on the upper portion;
Surrounded by a plurality of vertical surface portions made of corrugated cardboard, the vertical surface portion has substantially the same height as the vertical surface portion of the outer box, and the inner box housed in the outer box,
A plastic bag which is provided along the inner side of the vertical surface portion of the inner box, has an openable / closable zipper comprising a convex portion and a concave portion in the upper side opening portion, and the upper side portion is locked to the vertical surface portion of the inner box With
The upper side opening of the plastic bag is folded outward at the upper end of the vertical surface portion of the inner box, and is sandwiched between the upper end of the vertical surface portion and the outer box,
It is characterized by.

  In the simple toilet according to the present invention, since a plastic bag with a zipper is used as a urine storage bag, the airtightness after use is sure and hygienic. Further, a box on which a person sits for stool is composed of an outer box and an inner box made of corrugated cardboard. Also, the plastic bag is provided along the inner side of the vertical surface of the inner box, and the upper side portion is locked to the vertical surface of the inner box, so the plastic bag is a small size substantially along the inner peripheral surface of the inner box. The urine storage bag larger than necessary is not used. Also, the upper side opening of the plastic bag provided with the zipper is folded outward at the upper end of the vertical surface of the inner box and is located between the outer box and the inner box. The feces and urine do not adhere to the surface, and this point is also very hygienic.

  In the simple toilet according to the present invention, the upper side portion of the plastic bag may be locked in a notch formed in the vertical surface portion of the inner box, or locked in a hole formed in the vertical surface portion of the inner box. It may be. The upper side portion of the plastic bag may be locked to the vertical surface of the inner box by adhesion.

  Hereinafter, an example of a simple tray according to the present invention will be described with reference to the accompanying drawings.

(Refer 1st Example and FIGS. 1-6)
The perspective view of the simple toilet which is 1st Example is shown in FIG.1 and FIG.2. This simple toilet is composed of an outer box 1, an inner box 10 whose development is shown in FIG. 3, and a plastic bag 20 shown in FIG.

  The outer box 1 is formed by bending corrugated cardboard, and includes a vertical surface portion 2, a bottom surface portion 3 (see FIG. 6), a toilet seat portion 4, a closing lid portion 5, and a small lid portion 6 located on four sides. The outer box 1 is assembled in the shape shown in FIG. 2, and an inner box 10 having a plastic bag 20 is housed therein, and the small lid portion 6 and the toilet seat portion 4 are closed from above. The toilet seat 4, the closing lid 5 and the small lid 6 are foldable.

  The inner box 10 is formed by bending corrugated cardboard, has a cylindrical shape surrounded by vertical surface portions 11 located on four sides, and the left end 12 in FIG. The vertical surface portion 11 has substantially the same height as the vertical surface portion 2 of the outer box 1.

  The plastic bag 20 is a conventionally known bag made of plastic such as polyethylene, which is fused or welded. The upper side opening 21 is provided with an openable / closable zipper 22 including a convex portion and a concave portion. . As shown in FIG. 5 (A), the bag 20 is attached along the inside of the vertical surface portion 11 of the inner box 10 assembled in a cylindrical shape, with the zipper 22 opened, as shown in FIG. 5 (B). As shown, the upper end opening 21 of the bag 20 is folded outward so that both end portions 21 a are locked to the notches 13 formed in the vertical surface portion 11 of the inner box 10.

  The state in which the bag 20 is attached to the inner box 10 as described above is as shown in FIG. 2 as a perspective view. The inner box 10 with the bag in this state is stored in the outer box 1, and the small lid 6 and the toilet seat 4 are close. FIG. 6 shows an X-X cross section of the simple toilet assembled in this way. The upper side opening 21 of the bag 20 is folded outward at the upper end of the vertical surface portion 11 of the inner box 10, and the upper end of the vertical surface portion 11 is It is sandwiched between the small lid portion 6 of the outer box 1. Further, an appropriate amount of a water absorbing polymer (not shown) is placed in the bag 20.

  The simple toilet having the above configuration can be assembled and used on the spot. Before and after use, the toilet seat 4 is closed with the lid 5 and the lid 5 is opened for use. After use about 10 times, the zipper 22 is closed and the bag 20 is taken out and discarded. Since the bag 20 is provided with the zipper 22, the sealing property is reliable and hygienic.

  Moreover, since the box which a person sits down for a stool is comprised double by the vertical surface parts 2 and 11 of the same height, it has sufficient intensity | strength. Further, the bag 20 is provided along the inner side of the vertical surface portion 11 of the inner box 10, and both end portions 21 a on the upper side are locked to the notches 13 of the inner box 10. A small one approximately along the surface can be used, and an unnecessarily large urine storage bag is not required.
